| role of two triatoma (hemiptera: reduviidae: triatominae) species in the transmission of trypanosoma cruzi (kinetoplastida: trypanosomatidae) to man in the west coast of mexico. | from august 1997 to august 1998, 334 specimens of triatoma longipennis and 62 of t. picturata were collected in four groups of localities placed in the zone from guadalajara, jalisco to tepic, nayarit, in the west coast of mexico. most t. longipennis were collected outdoors (69.2%) while most t. picturata (58.1%) were collected indoors. all collected specimens were examined for trypanosoma cruzi infection, which was detected on 98 (29.3%) t. longipennis and 17 (27.4%) t. picturata. this study co ... | 2001 | 11285487 |
| colonization of rock pile boundary walls in fields by sylvatic triatomines (hemiptera: reduviidae) in jalisco state, mexico. | granite rocks is a very abundant material in mexico because they are used habitually as borders for fields. the current work established the significance of this ecotype as a colonization site for triatomines of the phyllosoma complex. seven sites, arbitrary selected, in san martin de hidalgo municipality (mexico) were investigated in april 2002 by using 210 mouse bait-traps left during the night in wall hollows. one hundred and seventy-two triatomines of all life stages were collected from the ... | 2004 | 15185954 |
| feeding patterns of triatoma longipennis usinger (hemiptera, reduviidae) in peridomestic habitats of a rural community in jalisco state, mexico. | we analyzed triatomine blood feeding patterns to evaluate the role of peridomiciles in trypanosoma cruzi transmission at the rural village of tepehuaje de morelos at jalisco state, mexico (1999). a total of 206 bugs were collected in 11 out of 26 households (42.3%). nymphs predominated in the collections (64.9% of the total). except for one triatoma barberi female, a species that belongs to the protracta species complex, all adults were triatoma longipennis, a species of the phyllosoma complex. ... | 2004 | 15605639 |
| importance of species of triatominae (heteroptera: reduviidae) in risk of transmission of trypanosoma cruzi in western mexico. | the epidemiological risk of infection by trypanosoma cruzi chagas in human populations of western mexico is still under study. although most vectors in this region and their vector capability are already known, new studies estimating the risk and the importance of individual triatominae species (hemiptera: reduviidae) for t. cruzi transmission are necessary. for 1 yr, every month, > 400 human dwellings and their surroundings in eight communities of two western mexico states were searched for tri ... | 2008 | 18533443 |
| [prevalence of triatomines (hemíptera: reduviidae: triatominae) infected by trypanosoma cruzi: seasonality and distribution in the ciénega region of the state of jalisco, mexico]. | the physical and geographical characteristics of the ciénega region, jalisco, mexico make it suitable for transmission of trypanosoma cruzi, the causative agent for chagas disease. this study characterizes the prevalence of triatomines infected by this parasite, their seasonality and their distribution in this region. a total of 328 triatomines were evaluated between january 2005 and june 2007, from 13 municipalities in the region. april, may and june were the months with the highest capture lev ... | 2008 | 18719805 |
| [monitoring triatomid bug (hemiptera: reduviidae) presence by sentinel chicken coops in southern jalisco state, méxico]. | chagas disease is an important public health problem in mexico. at least 30 triatominae species, vectors of that disease have been recorded, most with domiciliary habits and tendency to invade human dwellings. | 2010 | 20890558 |
| peridomestic colonization of triatoma longipennis (hemiptera, reduviidae) and triatoma barberi (hemiptera, reduviidae) in a rural community with active transmission of trypanosoma cruzi in jalisco state, mexico. | infestation of peridomiciles is likely a major risk factor for chagas disease transmission in jalisco state, mexico. an entomological and serological survey of a typical village was conducted between july and september 2003. the peridomestic areas of 100 dwellings were visited and triatomines were searched manually in 369 potential sites. a total of 1821 triatoma longipennis (93.2%) or triatoma barberi was captured. both species frequently occurred in sympatry. the infestation index was 60% for ... | 2007 | 17382891 |
| Population genetic structure of Meccus longipennis (Hemiptera, Reduviidae, Triatominae), vector of Chagas disease in West Mexico. | The originally wild species of the Meccus complex are important vectors of Chagas disease in Mexico. In West Mexico, Meccus longipennis plays an important epidemiological role. To understand the genetic structure of the domestic and wild populations of this species, a preliminary study with five polymorphic microsatellite loci was conducted. The population genetics analysis showed high structuring between peridomestic biotopes, with breeding subunits detected in a single peridomestic structure. ... | 2011 | 22142488 |
| natural crossbreeding between sympatric species of the phyllosoma complex (insecta: hemiptera: reduviidae) indicate the existence of only one species with morphologic and genetic variations. | the nucleotide sequences of the cytochrome b gene and the antennal phenotypes were analyzed for the following triatomine species: triatoma longipennis, triatoma pallidipennis, and triatoma picturata, which belong to the phyllosoma complex. these species inhabit sympatric areas from talpa de allende, autlan de navarro, and teocuitatlan de corona in jalisco, mexico. molecular marker analysis showed that the sympatric individuals are the natural crossbred descendents of different individuals living ... | 2010 | 20064999 |
